Advanced Nesting Issues

[gliebig]

I have a project that contains multiple pieces of 3 components and I'm having a heck of a time. I just started the 14 day trial of Advanced Nesting which would be a great application for this project. I've watched multiple videos (some are wrong) trying to learn this but I do have some issues with the workflow. I'm just trying to cut the panels in the design with a CNC router that have a material definition of coroplast 10mm.

First, the assembly is quite involved but I only need to extract 3 components. When the nest is created it scours the file for all components as there is no way to "pre filter" the components I want to nest. Then I get a huge table and there is no way to sort by material list so I have to uncheck all the components that aren't needed. Like angle iron, steel tubing, etc.

Then 16 of these panels are designed at 45 degrees in the model but that has no relevance on the manufacturing. They are just flat triangular shapes with drilled and shaped holes in them (lots of them). But the nesting takes those angels into consideration when building the nest so the layout of these pieces on the stock are at 45 degree angels and not lined up with the stock which makes sense.

So I copied these components to a new file and ran the nesting from there. Same issue with the panels at 45 degrees. I tried a simple nest with 16 pieces of each but the alignment did not work and the components were place at 45 degrees on the stock. 

So I aligned the components to the x-y wcs and made a rectangular pattern of each of the pieces with 16 of each and tried that nest. Yes this is defeats the purpose of advanced nesting and breaks the link to the design file. However, I did not change the nest from 16 of each to 1 of each and hit generate. BIG MISTAKE! There is no way to stop the nesting while it's generating wasting over an hour to compute something that was wrong from the start. I can't believe there isn't a way to cancel the operation!!!

After re-aligning the short panels are still at angles wasting lots of materials see Nest 2 screen shot.

I've attached the project file along with a screenshot showing the poor nesting from the design.

Is it 8,8 and 16 parts per star?

16 short ones, 12 long ones, and 4 long ones that are truncated. I didn't get anything close to what you show and it took nearly 40 minutes. I'm using an 1/8" diameter compression endmill so I have the spacing set to 0.135 and 2" offset from the bottom, 1" from sides.

OK I made some tweaks and made changes to the binding and setup. Generating the nests with the short panels bound took 30 minutes. I unbound that component and set the orientation to 45 degrees and the calculation time dropped to less than 5 minutes for the 32 parts. I have 32 gigs of ram and 90-94% was consumed calculating the nest. But when I generated the setups for CNC the WCS is not correct. Our machine has Y for the length and x as the width. Looking at the nest that would be in the upper left corner. I've attached the screen shots showing where hour home point is. What am I doing wrong?
